May - November (Low Season)
May through November experience its highest temperature. In late summer (September) the trade winds die which makes for the perceived temperatures even higher. July highs average 90F's, with August and September highs averaging in the mid-90s. If you don’t mind the heat it is the perfect time to visit the islands with less crowds and special travel deals.
The wet season starts in September, peaks in November, and tapers off by early January. Although most rain arrives in November, that month’s precipitation averages about 3.8 inches, much less than what you would experience on more northerly Caribbean islands. Since the Islands rainfall tends to be in brief bursts instead of sustained downpours, showers won’t limit outdoor activities for long.
